Additionally, if the only deep recursion problem is during GC, perhaps:

+++ gcc/cp/cp-tree.h 2011-06-08 14:15:06.743389464 +0200
@@ -4635,7 +4635,7 @@ struct cp_declarator {

/* A level of template instantiation. */
-struct GTY(()) tinst_level {

struct tinst_level *next;
could fix it and allow going back to 1024 from 900.
